feature request - read digital

[dmnewton]

Would it be possible to have a read digital that emitted a message when one or more of the digital inputs changed. When trying to react quickly to inputs (poling ever 10ms) the cpu load is very high.

Hi, in the moment there is no way to speed up the reading of the digits. I understand the challange.......

I had a go at geting the data faster and using less cpu - it's a little faster but far less cpu.
I realised reading the data via the SPI connection will be the limiting speed factor.

This is my first attemp at writing a node red package so it's basic.
